FEED FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent N 0. 671,587, dated April 9, 1901.

Application iiled June 4,1900. Serial No. 18,971. (Model-l feed mechanism for grain-drills; and its objects are to provide a device that will feed a great variety of grain and seed without clogging or leakage, to provide means for readily clearing the device of any particles of sand that may get into it, and to provide the device with various other new and useful features hereinafter more fully described, and

.particularly pointed out in the claims.

Our invention consists, essentially, in certain details of construction and arrangement of a feed mechanism for grain-drills, as hereinafter more fully described, reference being had to the accompanying drawings,in which- Figure l is a side elevation of a device embodying our invention; Fig. 2, a rear elevation ofthe same with parts broken away; Fig. 3, a vertical section of the same on the line 3 3 of Fig. 1; Fig. 4, a vertical section of the same on the line 4 4: of Fig. 2, and Fig. 5 a perspective detail of the gate.

Like letters refer to like parts in all of the figures.

Arepresents a portion of the driving-shaft, arranged to rotate and adjust longitudinally in any usual and convenient manner.

B is a cylindrical case wholly open at the side adjacent to the cup 0, except as partially closed by the said cup, and having a large central opening at the other side and having its axis coincident with the axis of the shaft A. This case is provided with an opening B at the bottom,opposite the reduced portion of the ring D, for the escape of anysand that may work in between the ring and case. The

case is also provided at intervals with projecting portions B, forming hearings to engage the ring D, which ring at its side adjacent the cup is provided with a circumferential enlargement D, engaging the inner surface of the case and forminga bearing-surface to support the ring, disk, and shaft. The ringD is also provided with in wardly-projectingtransverse ribs D, which slidably engage corresponding recesses E in the periphery of the disk E, which disk is provided with a suitable hub E at its side opposite the cup and projecting through the large opening in the case and fixed on the shaft to rotate and longitudinally adjust therewith. Extending down ward in front of the shaft and thence rearward be-.

neath the same is the cup 0, the same being open at the top to receive the grain or seed and also open at the side opposite the disk E and the upper part of the ring D. Said cup is also provided with a rearwardly-extended flange O at the top, having its face close to the side of the ring. The gate F extends within the ring and abuts at one side against the face of the disk and is provided near the middle with a sleeve F, within which the shaft A is freely rotative. This gate extends oppositely from the sleeve at substantially right angles and has a continuous smooth forward side and at its upper end is provided with a segmental extension G, having its outer or convex surface close to the path traversed by the inner angles of the ribs D' and movably abutting against the lower edge of the flange G. This flange and extension are of such di men sions that at all times one or more of said ribs are opposite the same. They thus efiectually prevent the escape of fine seed over the top of the gate and between the ribs of the ring. The forward surfaces of the gate and sleeve fit closely and slidably against the rear of the cup and close the space between the same and the disk and ring, except the opening at the bottom of the gate, where the grain escapes, which opening is varied, as usual, by adjustment of the shaft and disk longitudinally. The gate is held in place longitudinally by the disk at one side and the collar H at the other side and is'supported in place by the shaft.

By the construction herein shown the moving parts rest on the enlarged part D of the ring, and any wear is taken up by a slight downward movement of the ring, disk, and shaft, thus transferring the opening to the top, where it will do no harm. Further, if any sand should get between the case and ring too the ring can yield vertically, and the result is to avoid binding and grinding of the parts, as would be the case if the shaft were in an unyielding bearing of its own. By providing the bearing D at the side adjacent the cup at close joint at this sideissecured, and any sand in this hearing quickly works out opposite the reduced portion of the ring and escapes at the opening B. By providing the bearings B at intervals instead of continuous the sand quickly escapes from between the side of the ring and the case. It will be observed that there are no obstructions or projections within the cup to inter: fere with the flow of the seed or grain and cause it to brid e and han up in the cu wheel rotative in the case and having a circumferential bearing engaging the bottom of the case, and a shaft in the axis of the wheel and supported by the wheel, substantially as "described.

2 The combination of a case, a ring rotative in the case, a shaft in the case, a disk on the shaft and slidably engaging the ring, and

T a circumferential bearing on the ring engaging the interior of the case and supporting the ring, disk, and shaft, substantially as described.

3. The combination of acase, a shaft in the axis of the case, a disk attached to the shaft, a ring surrounding the disk and driven thereby, a circumferential bearing on the ring engaging the interior of the case, and raised portions on the case engaging the side of the ring at intervals, substantially as. described.

4. The combination of a case open at one side and having a bottom opening, a cup partially closing the open side of the case andopening into the same, a shaft in the case, a disk on the shaft, a ring rotative in the case and driven by the disk, a circumferential enlargement on the ring at the side adjacent to the cup, said enlargement forming a bearing engaging the case and supporting the ring, shaft, and disk, substantially as described.

5. The combination of a case open at one side and having a large axial opening at the ring at one side and having a flange abutting against theside of the ring,and a gate in the interior of the ring having an extension within the ring, said extension havingits surface close to the path of the ribs on the ring, substantially as described.

7. The combination of a rotating ring having internal ribs, a disk having recesses movably engaging the ribs, a cup partially closing the side of the ring, a gate within the ring and engaging the disk at one end and partially closing the rear of the cup, a flange on the cup adjacent to the sides of the ring, and a segmental extension on the gate adjacent to the ribs on the ring, substantially as described.

8. The combination of a case'open at one side and having a large axial opening at the other side, a ring rotative in the case and having a circumferential bearing engaging the interior of the case, a shaft in the axis of the case, a disk on the shaft having a hub at one side projecting through the axial opening of the case and fixed on the-shaft, a cup partially closing the open side of the case and opening into the case, a gate having a continuous smooth forward side partially closing the rear of the cup and having a sleeve, in which sleeve the shaft is rotative, substantially as described.

9. The combination of a case open at one side, a ring rotative in'the case and having internal ribs and a circumferential bearing engaging the case, a cup partially closing the open side of the case, a flange on the cup adjacent to the side of the ring, a gate anda disk within the ring, and a segmental extension on the gate having its outer surface close to the ribs on the ring, substantially as described.

In testimony whereof we aflix our signatures in presence of two witnesses.
